I think both sides of the argument can be valid, depending how you interpret "GPU spec". If GPU spec means raw horsepower then yeah Xbox couldn't touch high end PC configurations at launch.
When I wrote this I meant that it was absolutely the best technology that Microsoft could have put in the console considering price, power limitations features and performance. In terms of that, Xenos was on par with any PC card if not better until x1950 came out 6 months later.
This all ties in to the argument how people are assuming that Xbox 720 will have a 6670 which is ridiculous because Microsoft knows what they are doing. Maybe 6670 in quad crossfire lol...
Thinking back to 2006 when PS3 launched, imagine if they went all out and got the latest and greatest GPU at the time, the 8800GTX. This would have made PS3 next next gen as 8800GTX (9800GTX or GTS250 are the same card) still are competent GPUs.
